When store manager Kent Miller was shown pictures of the cup and was asked if this was something Starbucks condones, he said, “No, we definitely don’t condone, but let me find more about this, and I will talk to my boss.”

The customer wrote a note on the same cup and left a message for the baristas in hopes these employees won’t judge other people. The note reads, "2 of my sisters are diabetic, so ... not funny."

“We strive to provide an inclusive and positive experience for our customers, and we're disappointed to learn of this incident," Starbucks corporate headquarters said in an email. "We are working directly with the customer to apologize for his experience, and with our partners (employees) to ensure this does not happen again."
